What is an EFI file?

Files with the .efi extension are most commonly associated with Extensible Firmware Interface files. These files define the interface between platform firmware and a user's operating system. They create the environment for booting the user's operating system and running various pre-boot applications. The .efi file extension is also used for Microsoft Windows 7 files.
